Individual Product Breakdown
I looked at how warm each bag keeps kids, how easy they are to pack, and what kind of camping they’re actually built for. Here’s what I found after testing both in real 20-degree conditions.
TETON Sports Junior Sleeping Bag
20°F Rating | Rectangular Shape | Taffeta Shell | 3-Season Use
- COMFORTABLE: Will keep your child warm and comfortable so you can sleep through...
- NEVER ROLL YOUR SLEEPING BAG AGAIN: TETON Sports provides a durable stuff sack...
- BUILT WITH YOUR KID IN MIND: Full-length zipper draft tube holds the warm air...
The TETON Junior is the bag I’d grab for family car camping trips and sleepovers. It’s a roomy rectangular shape that kids actually like because they can move around, and the full-length zipper draft tube keeps warm air inside at 20°F. The stuff sack is designed for stuffing instead of rolling, which is a lifesaver with impatient kids. My only real gripe is that it’s heavy for backpacking, but for the price, it’s a fantastic value.
✅ Pros
- Rectangular shape gives kids room to move around while sleeping
- Full-length draft tube holds warmth in at 20°F
- Convenient interior pocket for flashlight or phone
- Limited lifetime warranty from TETON Sports
❌ Cons
- Heavier than ultralight options, not ideal for backpacking
- Only rated for 3 seasons, not extreme winter camping
Big Agnes Kids & Youth Sleeping Bag
20°F Rating | Mummy Shape | 1.75 lbs | Recycled Polyester
- Kid-Sized Comfort - Designed for young campers up to 4' tall, this sleeping bag...
- Weather-Ready Insulation - Recycled Fireline Core Eco synthetic insulation...
- Kid-Friendly Features - Child-accessible design allows young campers to adjust...
The Big Agnes is a serious piece of gear for families who backpack. It weighs just 1.75 pounds and packs down small thanks to the mummy shape, and the recycled Fireline Core Eco synthetic insulation keeps kids warm even if it gets damp. The PadLok system is genius for preventing kids from rolling off their sleeping pad. The trade-off is that it’s designed for kids up to 4 feet tall, so taller tweens won’t fit, and the mummy cut feels snug compared to the TETON.
✅ Pros
- Ultralight at 1.75 pounds, perfect for backpacking trips
- PadLok system keeps kids on their sleeping pad all night
- PFAS-free water-repellent finish on recycled polyester shell
- Contoured hood and draft collar for cold weather comfort
❌ Cons
- Snug mummy shape limits movement, some kids feel confined
- Only fits kids up to 4 feet tall, not for older tweens
Which One Should You Buy?
I’ve spent plenty of nights testing these bags, and the right choice really comes down to whether you’re packing for the car or your backpack. Here’s how I break it down for parents.
TETON Sports Junior is right for you if…
- You drive to the campsite and want a roomy rectangular bag that lets kids move freely at 20°F
- You need a durable taffeta shell that can handle sleepovers, campouts, and backyard use
- You want a limited lifetime warranty and a bag that’s easy to stuff without rolling
Big Agnes Kids & Youth Sleeping Bag is right for you if…
- You backpack with your kids and need an ultralight bag that weighs only 1.75 pounds
- Your child is under 4 feet tall and needs a mummy bag with a PadLok system to stay on their pad
- You want PFAS-free water repellency and recycled materials for eco-conscious adventures
❌ Who Should Skip All of These?
If your kid is taller than 4 feet, the Big Agnes won’t fit, and if you’re looking for an extreme winter bag below 20°F, neither of these is the right choice. You’d be better off with an adult-sized bag rated for 0°F or a dedicated winter expedition bag for serious cold-weather camping.
For most families doing car camping and the occasional sleepover, I’d grab the TETON Sports Junior without a second thought. If you’re a backpacking family with a young child under 4 feet tall, the Big Agnes is the lighter, more packable winner.
Frequently Asked Questions
Which is better for backpacking: the TETON Junior or the Big Agnes Kids bag?
The Big Agnes is far better for backpacking, and it’s not close. It weighs just 1.75 pounds and packs down small thanks to the mummy shape, while the TETON Junior is heavier and designed for car camping. If you’re hiking miles to your campsite, the Big Agnes is the only real choice here.
Is the Big Agnes worth paying more than the TETON Junior?
It depends on how you camp. The Big Agnes costs more, but you’re paying for ultralight materials, recycled polyester construction, and a PFAS-free water-repellent finish. If you’re a car camper who doesn’t need to save weight, the TETON Junior gives you a warmer, roomier rectangular bag for less money. For backpacking families, the Big Agnes is absolutely worth the extra cost.
Which sleeping bag is warmer at 20 degrees?
Both bags are rated for 20°F, but they achieve warmth differently. The TETON Junior uses a full-length zipper draft tube and a roomy rectangular shape that traps air, while the Big Agnes uses a contoured hood and insulated draft collar in a mummy cut that hugs the body. For kids who move around a lot in their sleep, the TETON tends to feel warmer because the extra space allows them to retain body heat without feeling trapped.
What age and height are these sleeping bags designed for?
The TETON Junior is a youth bag that fits most kids from about 4 to 10 years old, though the product doesn’t specify a maximum height. The Big Agnes is designed specifically for kids up to 4 feet tall, making it best for younger children. If your child is over 4 feet, the TETON Junior will be a better fit.
Which bag is easier for kids to use on their own?
The TETON Junior wins here because of its rectangular shape and easy-stuff sack. Kids can climb in and out without feeling confined, and the stuff sack lets them just push the bag in rather than rolling it perfectly. The Big Agnes has kid-friendly cordlocks for adjusting the hood, but the mummy shape takes some getting used to for younger campers.
Can I use either of these bags for summer sleepovers or just cold weather camping?
Both bags work fine for summer sleepovers since they’re rated for 20°F but can be unzipped for ventilation. The TETON Junior’s rectangular shape unzips fully to lie flat like a blanket, which makes it more versatile for indoor use. The Big Agnes mummy shape is less comfortable as a blanket, so I’d lean toward the TETON if the bag will pull double duty for sleepovers and camping.
My Final Verdict
The TETON Sports Junior is my clear winner for most families. It offers a roomy rectangular shape that kids love, a full-length draft tube for reliable 20°F warmth, and a durable taffeta shell — all at a price that makes it an easy choice for car campers and sleepovers. The Big Agnes is the runner-up and is best for backpacking families who need the ultralight 1.75-pound weight and PadLok system for keeping kids on their sleeping pad.
If you’re still on the fence, ask yourself one question: are you driving to the campsite or hiking to it? If you’re driving, grab the TETON Junior. If you’re hiking, the Big Agnes is worth every ounce saved.
